HARRISON S. MILLER, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TO WILLIAM H. MARTZ, OF SAME PLACE.

WATER-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 257,509, dated May 9, 1882.

Application filed July 16, 1880. (Kb model.)

To all whom it may concern Be it known that I, HARRISON S. MILLER, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in 'Water-Governors,

of which the following is a specification.

The object of my invention is to produce a perfectly-balanced water-governor which will act under all circumstances with certainty and celerity. Thisis accomplished by passing the valvethrough the bottom of the receiving-chamberintoa separate chamber below and connecting such lower chamber with the discharging chamber on the opposite side of the receiving- 1 5 chamber therefrom by means of a tubular connection through the valve and valve-stem.

Referring to the accompanying drawings, which are made a part hereof, Figure 1 is a side elevation of a water-governor embodying my improvements, and Fig. 2is a vertical section through the center of the same.

In said drawings, the portion marked A represents the casin g or cylinder of my improved governor; B, avalve-seat, preferably castiu one .2 5 piece with said casing, which divides said casing into two chambers, G andD; G, areceivingchamber, into which the water enters through the pipe 0 5 D, a second chamber, from which the water is discharged through the pipe D 5 0 E, a valve of peculiarconstruction,which is arranged to close the orifice b in the valve-seat B, and thus cut off communication between the two chambers when the water -pressure becomes great enough to cause the governor to 3 5 act; I, the valve-stem connecting the valve with the plunger; G, a plunger, made watertight with the cylinder, by means of which the water-pressure is enabled to operate the valve H, the stem to said plunger, connecting it with the lover I; J, a weight which is adj ustably mounted on the hinged lever I, and by which the amountof pressure necessary to operate the governor is determined and K, a third chamber below the chamber (J, into which the lower 4 5 end of the valve E extends, and which connects through the small tubular openings 0 f with the upper or discharging chamber, D.

The operation of my governor is as follows: The water enters through the pipe 0 into the chamber 0, from which it passes through the orifice bin the valve-seat B into the chamber D. When the water-pressure in the chamberD exceeds the force exerted by the weight J the plunger G is forced up, carrying with it the valve E,thus closing the orifice b and prevent 5 ing the ingress of any more water into the chamber D. Whenever water is drawn off through thepipeDor itsconnections thepressure in the chamber D is of course reduced, and the valve is forced back by the action of the weight J, so as to admit more water.

If the valve E were constructed in the ordinary way, the pressure of the water upon the under side thereof in the chamber 0 would prevent it from falling back at the proper time. I have therefore constructed the valve of an equal size throughout and extended it through a stuffing-box, a, in the lower end of the cylinder, so that its lower end shall not be affected by the pressure of the water in the chamber (3, which obviates suchdisadvantage. To still more perfectly secure the result last mentioned Icause an equal pressure to come upon the two ends of the valve when the same is closed by forming a chamber, K, around thelower end of the valve, below the stuffing-box a. Said chamber is formed by chambering the nut or projectionL that sets up the packin g around the valve and I connect the chamber K with the chamber D by means of a tubular opening, 0 f,through 8c the valve itself and its valve stem. By this means a perfectly equal pressure is maintained on all the corresponding parts of the valve, and the governor is therefore enabled to respond to the slightest variation in the pressure of the 8 5 water, and the pipes in the building connect ing with the discharging-pipe D are therefore always guarded against the danger of overstraining,notwithstanding any increase in the outside pressure. 9

The nut L has a double function. The said third chamber, in connection with the tube 6 and f, acts as a cushion or governor to the plunger, preventing j erkin g or violent movement of the plunger and valves when water is with- 5 drawn, let in, or cutoff. The said nut L is also used to set up the packing around the plunger or valve between the chambers K and U.

I do not claim broadly the device shown in the reissue patent of Bartholomew, May 15, 1866, No. 2,241.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

In a water-governor, the combination of the two chambers U D, divided by the partition B, which also forms the valveseat, an d connected by the opening I) through said partition, the weighted stem H F, the plunger G, chambernut L, stuffing-box a, and valve E, the latter being of equal size throughout and extending through into the third chamber, K, and provided with the orifice of, leading from said 15 third chamber through into the upper or dischargingchamber, D, all constructed, arranged, and operated substantially as shown and described, and for the purpose specified.

In witness whereof I have hereunto set my 20 hand and seal, at Indianapolis, Indiana, this 12th day of July, A. D. 1880.
